The by-product of eating Mexican food the night before. What happens when you let all that food sit overnight, and then in the morning it comes out of you completely liquid. Hence the Swiss Miss and the Piss.

Last night I ate half a crave case from White Castle and when I got home I went right to sleep. I woke up and when I got to the bathroom all that came out was Swiss Miss and Piss.
